feel for how the exam is administered, but this "practice exam" contains no sample questions. Once an applicant has been approved to sit for the exam, he or she has 90 days in which to schedule an examination date with Prometric. Past exams from 2002 and 2003 are available from the USPTO online without cost. Prerequisites General The USPTO requires that all those applying for registration (agents or attorneys) meet three requirements: (1) good moral character, (2) legal, scientific and technical qualifications necessary to render valuable service, and (3) competence to advise and assist patent applicants in the presentation and prosecution of patent applications. The registration exam primarily addresses the third requirement. The second requirement is typically met with a bachelor's degree in a recognized technical subject; the USPTO calls this "Category A" eligibility. These fields include biology, chemistry, computer science, most engineering disciplines, and physics. Two other options are available to satisfy the second requirement: having enough semester hours of specific science courses ("Category B") or passing the Fundamentals of Engineering exam ("Category C"). Note that the requirements for Category B eligibility are considerably more onerous than for Category A—not only must the candidate provide official college transcripts, he or she must supply a copy of the official course description, concurrent with the year that the course was taken, for each course used to establish eligibility for the exam. Degrees in the philosophical arts (such as pure mathematics) or the social sciences (such as sociology) are not sufficient by themselves to meet the technical training requirement. However, the scientific and technical training requirement can be fulfilled by submitting proof of 40 semester hours of undergraduate courses in the above fields, 8 of which must consist of either two consecutive semesters of physics for scientists and engineers with laboratory or two consecutive semesters of general chemistry with laboratory. Consecutive means that the two courses cover one curriculum, such as physics 101 and 102. All 40 semester hours can be completed at community colleges and do not have to result in any bachelor of science degree. All of the courses must be applicable towards a degree in the subject. For example, physics with calculus would count, while physics without calculus, usually taken by other majors, would not. Other Category B qualifications allow for one without a bachelor's degree in a listed field to also demonstrate he or she has had 24
